IMAGE DESCRIPTION:
This image show how nature can at least wins against man. Where once the majesty
of man-like gods ruled, now tress, grass and animals live in peace. There,
where once was home for Mars or Venus now it's the confortably house for a
lonley cat.
DESCRIPTION OF HOW THIS IMAGE WAS CREATED:
I used a lot of techniques to finsh this entry.
1 - Terrain
With Terragen I build the terrain and saved it as a .raw file. Then I used PSP
to convert it as a grayscale tga and used it in a Heightfield. To speed up the
raytracing I raytraced the ground texture in Terragen as well, using an ortho
camera with the same light coming from the same place then in PovRay (well, I
tried...) after severals tries I achieved a not-so-good result, but it's the
best I could :-)). This Terragen image has been then mapped onto the
heightfield.
2 - Vegetation
I created 3 kind of background trees and 4 kind of grass with tree.inc and
grass.inc by Gill Tran respectively. I then "platend" them onto the heightfield
using the trace command in conjunction with different random macros. A total of
about 4.000 trees and about 10.000 grass patches have been planted.
Both textures came from actual leaf and grass pictures from wich I grabbed the
colour using the dropper tool in psp.
The foreground tree is a Gilles Tran macro tree as well. It required almost 1
hour to be created.
3 - Light
Light is the wonderfull lighsys.inc by Jaime Vives Piqueres. I made several
tries but at least I achieved a good result IMHO.
4 - Temple
All the colum and the front end of the temple is done with my macro archi.inc (I
will share it someday!!) and it's all CSG and the broken colums are isosurface.
To speed up rendering I'm planning to convert everything to mesh (probably in
the far future :-))
5 - Cat
The cat is a free 3ds object found at www.3d-cafe.com I exported using the
good-old dos program 3ds2pov.
6 - Rendering
I rendered the image in two phases. The first trace was done at 320x240 with
simplified objects only to save radiosity data, then I traced at final
resolution (with all the regular objects) loading the radiosity data saved
before. Go to see Jaime Vives Piqueres site if you want to know more
(www.ignorancia.org).
The camera has a small focal blur to add depth.
If you're still reading you are a great one :-)
